A method for electing a representative node device performed by a first node device in a blockchain system includes: broadcasting candidate addition transaction data in the blockchain system, the candidate addition transaction data carrying credential data, the credential data being received from a target server and indicating that a first node device meets a qualification requirement for a candidate node device; storing the candidate addition transaction data on a target blockchain of a blockchain system when a plurality of node devices in the blockchain system verify the candidate addition transaction data by consensus; and participating in an election of the representative node device according to the candidate addition transaction data stored on the target blockchain.

Method and apparatus for electing representative node device, computer device, and storage medium

Embodiments of this disclosure disclose a resource transfer data management method and apparatus, and a storage medium, which belong to the field of Internet technologies. The method includes: receiving transaction data transmitted by a first server, wherein the transaction data is obtained by the first server by signing resource transfer data according to a private key of the first server; verifying the transaction data according to a public key of the first server; and generating a second block according to the transaction data and a feature value of a first block in a blockchain when the verification succeeds, and adding the second block as a next block of the first block to the blockchain.

Resource transfer data management method and apparatus, and storage medium

A method for electing a representative node device for a blockchain system includes: receiving IP address information of a first node device, the first node device being in a candidate state for a representative node device; receiving, from the first node device, an IP address obtaining request for requesting IP address information of a representative node device; when the first node device is determined to be a representative node device of the blockchain system elected in a current election process, transmitting, to the first node device, an IP address list comprising IP address information of representative node devices elected in the current election process; and when the first node device is determined not to be a representative node device of the blockchain system elected in the current election process, skipping the IP address obtaining request.

A method for electing a representative node device is performed at a blockchain system, including: obtaining voting transaction data from the node devices, the voting transaction data being used for voting for one or more node devices of the blockchain system as representative node devices; generating and storing the voting transaction data into a target blockchain of the blockchain system when a plurality of node devices of the blockchain system verify the voting transaction data by consensus; and when a quantity of blocks in the target blockchain generated using the voting transaction data reaches a preset quantity, determining an election result according to quantities of votes of the node devices determined from the voting transaction data, the election result identifying a plurality of representative node devices in the blockchain system being configured to generate new blocks for the target blockchain and perform verification on the new blocks by consensus.

A data backup method includes querying a first block of a first blockchain for unused transaction output information based on a first condition being met, the first block including each block of all blocks included in the first blockchain; generating transaction information according to the unused transaction output information obtained based on the querying, the transaction information indicating a transaction operation based on an account address to which the unused transaction output information belongs; recording the transaction information in a second block and releasing the second block, and recording the second block on which a consensus is reached on a second blockchain; and backing up the first blockchain into a storage system, and deleting the first blockchain. Counterpart apparatus, terminal, server, and/or non-transitory computer-readable medium are also contemplated.

Data backup method, storage medium, and computing device

A terminal for generating music may identify, based on execution of scenario recognition, scenarios for images previously received by the terminal. The terminal may generate respective description texts for the scenarios. The terminal may execute keyword-based rhyme matching based on the respective description texts. The terminal may generate respective rhyming lyrics corresponding to the images. The terminal may convert the respective rhyming lyrics corresponding to the images into a speech. The terminal may synthesize the speech with preset background music to obtain image music.

Method and apparatus for generating music

An object information processing method includes obtaining an information creation request. The information creation request carries a first address identifier of a target object. The target object includes a subdirectory or a sub-file. The method further includes determining a second address identifier of a parent directory to which the target object belongs according to the first address identifier, searching for an information storage area storing metadata of the parent directory according to the second address identifier, and performing data updating for the information storage area according to the first address identifier to create an association relationship between the parent directory and the target object in the metadata.
